When starting work on a new project that requires motion control, one of the most important considerations is what bearings to use.
It's easy to fall back on what you've been using for years instead of rocking the boat with new ideas or concepts. You might be more inclined to stick with bulky, robust steel or bronze bearings without thinking about the upsides of plastic bearings. However, in most applications, plastic spherical bearings deliver a better performance than their metal counterparts.
General questions typically asked when considering which bearings are right for an application include: what type of bearings will operate seeminglessly in tough environments; what type of bearings can withstand a wide range of loads, speeds and temperatures; and what type of bearings will possess the necessary features to prevent premature failure?
Here are six reasons why design engineers should consider using plastic spherical bearings:
